It is the process of branching of pipeline while product is being transported through the pipeline. So it is a very special technology, which I would like to know in detail or would like to get link of any website to go through for the same.

Hot Tapping is employed as a means of providing a branch connection to a live pipe in constant operation, where the consequences of a shutdown would not be practicable. This method uses a short section of pipe, to which an isolating valve is either welded or fitted mechanically. After fitting - and with the valve in the open position - the pipe is drilled to the maximum permissible size through the valve. On completion of the drilling operation the valve is closed, and the drilling equipment removed.
This process can be completed without leakage or loss of flow and can be used on almost any type of pipe (iron, steel, plastic, concrete) carrying liquids at high temperatures and under pressure.

If you go to http://www.tdwilliamson.com/hottaptdw/tap_Machine.html and follow links you will get information. There are now procedures even for hot tapping large sub sea pipelines in situ. Don't know the details of this.
